We covered the more difficult way last time; now we&#8217;ll do the easier way.<\/p>\n<p>Example: add 3<sup><span style=\"font-size: medium;\">2<\/span><\/sup>\u2044<sub><span style=\"font-size: medium;\">5<\/span><\/sub> + 4<sup><span style=\"font-size: medium;\">6<\/span><\/sup>\u2044<sub><span style=\"font-size: medium;\">7<\/span><\/sub><\/p>\n<p>Step 1: Convert the mixed numerals to improper fractions.<\/p>\n<p>Recall that to do so, you multiply the whole number by the denominator, add the numerator, then put the answer over top the same denominator:<\/p>\n<p>3 2\/5 = (3&#215;5+2)\/5 = 17\/5<\/p>\n<p>Similarly,<\/p>\n<p>4 6\/7 = 34\/7<\/p>\n<p>Our problem is now transformed into<\/p>\n<p>17\/5 + 34\/7<\/p>\n<p>Step 2: Add the improper fractions.<\/p>\n<p>As always when adding fractions, we need common denominators.<\/p>\n<p>(17&#215;7)\/(5&#215;7) + (34&#215;5)\/(7&#215;5) = 119\/35 + 170\/35 = 289\/35<\/p>\n<p>Step 3: We would reduce if 289 and 35 shared a common factor, but they do not. If desired, we can put the answer back into a mixed numeral. We divide 289 by 35 to get 8 remainder 9. 8 becomes the whole number part of the mixed numeral, while 9 goes back over 35:<\/p>\n<p>289\/35 = 8 9\/35<\/p>\n<p>A few points:<\/p>\n<p>1) Although this method is more straightforward than the <a href=\"?p=2650\">previous one<\/a>, it does lead to handling bigger numbers. If big numbers bother you, you&#8217;ll likely prefer the previous method.<\/p>\n<p>2) From grade 11 on, you rarely see mixed numerals in academic math; improper fractions are preferred. However, trades math continues to prefer mixed numerals.<\/p>\n<p>3) If a question was posed in mixed numeral form, you are likely expected to give your final answer as a mixed numeral if possible.<\/p>\n<p>I&#8217;ll be covering other operations with mixed numerals in future posts.<\/p>\n<p>Jack of <a href=\"https:\/\/www.oracletutoring.ca\">Oracle Tutoring by Jack and Diane,<\/a> Campbell River, BC.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tutoring math, you meet adults upgrading for new careers. \u00a0The tutor continues with this topic, which is common on entrance tests.
